摘要:
A differential absorption spectrum for a reactive gas in a gas mixture can be generated for sample absorption data by subtracting background absorption data set from the sample absorption data. The background absorption data can be characteristic of absorption characteristics of the background composition in a laser light scan range that includes a target wavelength. The differential absorption spectrum can be converted to a measured concentration of the reactive gas using calibration data. A determination can be made whether the background composition has substantially changed relative to the background absorption data, and new background absorption data can be used if the background composition has substantially changed. Related systems, apparatus, methods, and/or articles are also described.
摘要:
Initial source and target models are divided into segments responsive to at least one segmentation rule. After changes, post-change source and target models are likewise divided. The at least one segmentation rule is defined responsive to at least one transformation rule such that use of the at least one segmentation rule divides initial source and target models into corresponding segments. Change statuses are identified regarding initial segments relative to post-change segments of the respective models responsive to comparing initial segments to post-change segments of the source model and initial segments to post-change segments of the target model. An indication of conflicts between the post-change source model and post-change target model is generated for presentation to a user or to a computer automated conflict settlement process. The generating is responsive to comparing the identified change statuses of the corresponding segments of the initial source model and initial target model.
摘要:
A system modeling facilitating method and apparatus, wherein, entities and interactions among the entities are introduced gradually starting from critical entities in a system to form an abstract view of the entities. An associated sub-module is built for at least one of the entities and interfaces to other entities are formed for the sub-module. Representations of behaviors and logical relations among the behaviors, as well as links between its interfaces and representations of behaviors are built. When an entity is extended to be a sub-module, other entities appear in abstract form, forming a local view of sub-module together with the other entities shown in abstract form. A global view can be formed by combining the sub-modules depicted in the local view based on the interaction described in the abstract view.

A modular asynchronous contactor assembly includes a contactor for each phase or pole of an electrical device. The contactor assembly is applicable as both a switching device and an isolation or load protection device. As such, each contactor is constructed so that each includes multiple contact assemblies. Moreover, the contactors within a single contactor assembly or housing can be independently controlled so that the contacts of one contactor can be opened without opening the contacts of the other contactors of the contactor assembly.
摘要:
A method and apparatus to independently control the closing or making of contactors in a modular contactor assembly is disclosed. The apparatus includes a contactor assembly having multiple contactors such that each contactor is separately controlled such that one contactor may be closed without the other contactors of the assembly being closed. The contactors are arranged such that a pair of contactors is caused to close following a zero-voltage crossing of a power signal. A third contactor is caused to close after the pair of contactors has closed.

摘要:
Control of an induction motor is carried out to limit damaging arcing stress and mechanical stresses placed on the control contactor assembly and the induction motor resulting from the simultaneous or synchronous breaking and making of contactors employed to connect the windings of the motor to a power supply. Asynchronously connecting the windings to the power supply via the asynchronous or non-simultaneous closing of the contactors of a modular contactor assembly reduces the potentially damaging transient current, the associated torque oscillations, and mechanical stresses. The present invention is particularly applicable to delta motors that are started with its windings in a star or wye configuration followed by the reconnection of the windings in a delta configuration when the motor is at normal running speed.
摘要:
An alternating current circuit breaker having an extended fin cantilevered from its housing. A portion of the fin along its extended length is magnetized so that the fin flutters in the magnetic field generated by the alternating current conducted through the breaker. The resulting magnetic resonance vibration establishes forced, convective heat transfer which assists cooling of the breaker.
摘要:
Particular embodiments described herein can offer an electronic fabric for a processing system that includes a fabric adapter to couple to a first fabric associated with a first system and to couple to a second fabric associated with a second system. The fabric adapter is configured to pass bidirectional communications between the first system and the second system. The electronic fabric can further include an address translation agent configured to map a first physical address in a first address space of the first system to a second physical address in a second address space of the second system.
